Our fan keeps turning off in the middle of the night and then immediately back on. This process will repeat all night until you turn it off.

1. Faulty thermostat
2. Faulty blower
3. Faulty furnace control board

Turn the power off and unplug the machine for 60 seconds. Plug the machine back in and turn power on. Repeat this process up to 3 times until the F4 error code has cleared.

Make renovation bios ( by service tag ) And , of course, choose from standard mode BIOS "default" .
Colors of black and red plug in any fan
good Luke

Your going to need to replace the main board, there is a regulator IC that is bad causing this

turn the power off and leave it off for 1 hr to cool down it should be ok after but if not the relay has burnt out

What is the model number of your tv?

The best solution on earth!!!
the same thing happened to me. all you do is press the eject button until it turns yellow. when that happens, immediately unplug the ac cord, & plug it back in. repeat this process until the light stays green! trust me, it works. it saves alot of money too if your warranty has ran out

To turn the fan off, press the "fan key" until it says "auto". This will turn the fan off. When the programs scheduled, changes, the fan will go on again. You have to repeat the fan to "auto" each time the schedule changes.

Hi,

Can think of only three possibilities:
1. CPU fan motor, bearings needs lubrication or replacement;
2. Power Supply fan motor, same as above or any of the other fans;
3. Hard disk spindle motor (though unlikely).

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.
